A 10.8-year-old, spayed female toy poodle presented with an esophageal foreign body. The foreign body was removed endoscopically, and a gastrostomy tube was placed to provide nutritional support during esophageal healing.
The gastrostomy tube was later removed by endoscopic retrieval of the bulb through the esophagus.
Immediately afterward, the dog developed hemothorax and eventually died.
It was determined that many small arterial branches were avulsed from the aorta. The involved sections of aorta histopathogically evidenced medial necrosis, which was believed to be related to a prior disruption of blood flow through the vasa vasorum.
